AMBULANCE-SPRING.

SPECIFICATION forming part of Letters Patent No. 359,388, dated March15, 1887. Application filed January 25, 1887. Serial No. 225,462. (Nomodel.)

The ordinary form of vehicle-spring, which is necessarily arranged tosupport the weight of a wagon-body, is not adapted to insure thatperfect freedom from all jolt or jarring which is so desirable in thetransportation of the sick or wounded, and it is to provide for thecomfortable transportation of those who are too ill to sit up or whohave met with accidents that we have devised a novel ambulance-spring,that is illustrated in the drawings, and which will be hereinafterdescribed, and specifically pointed out in the claims, the object of thepresent invention being, as above intimated, to provide a spring whichwill act to relieve the patient from all undue shock or jar.

Reference is to be had tothe accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a cross-sectional view of a portion of an ambulance-bodythat is provided with our improved form of spring. Fig. 2 is an enlargeddetail view, certain port-ions of the apparatus being shown in section.Fig. 3 is a face view of one of the springs and its attachments, thespring-caps being shown in section. Fig. 4 is a still further enlargeddetail view of one of the spring-supported hooks, the hook-shank, itsroller-supporting lug, and the main standard of the apparatus beingshown in section ,and Fig. 5 is a sectional view of one of thesupportingbrackets.

In the drawings, 10 represents the body of an ordinary form ofambulance, the side lockers of the ambulance being shown at 11. To theapproaching faces of thelocker-walls we secure two lower brackets, 12,and two upper brackets, 13, the brackets 12 being arranged to receivethe lower ends of standards 20, while the brackets 13 are arranged'toreceive downwardly-extending lugs or projections 14, that are riveted orotherwise rigidly secured to the standards 20. The upper ends of thestandards 20 are formed with hooks 15, upon which there are suspendedstirrups 16, which carry lower spring-caps, 17, said caps supportingsprings 18, which carry caps 19. The caps 17 and 19 are centrallyapertured, and within each aperture so formed there is arranged theshank 21 of a hook, 22, the upper end of said shank being secured to ablock, 23, that rides between the parallel lengths of the stirrup 16.The hook 22 is formed with a lug or projection, 24:, which extendsthrough a vertical slot, 25, that is formed in the standard 20, and tothe inner end of this lug or projection 24 there are secured twoanti-friction rolls, 26, (see. Fig. 4,) which are arranged to bearagainst the outer face of the standard 20 upon either side of the slot25.

From the construction described it will be seen that the standards 20and the parts carried thereby may be readily removed from theirconnection with the ambulance-body, and when not in use the said partsmay be stored away in the lockers, but when needed the standards may bequickly adjusted to place.

In operation the standards are set up as indicated in Fig. 1, the fourstandards being arranged in pairs, two being located at the forward endand two at the rear of the vehicle,

the hooks 22 being arranged to receive the side poles, 30, of astretcher, 40, and when the stretcher has been placed as indicated inFig. 1 the springs 18 will act to relieve the patient carried by thestretcher from all undue shock or jar.

Having thus fully described our invention, we claim as new and desire tosecure by Letters Patent 1. The combination,with a standard formed witha hooked upper end, of a stirrup connected to the standard, a springsupported by the stirrup, and ahook supported by the spring and providedwith a projection engaging the standard and holding the same looselythereto, substantially as herein shown and described.

2. The combination, with a standard, of a stirrup supported thereby, aspring supported by the stirrup, a hook supported by the spring andformed with a projection which extends through a slot formed in thestandard, and antifriction rolls carried by the said projection,substantially as described.

3. The combination, with a standard formed with a hooked upper end, of astirrup carried thereby, a spring-cap connected to the stirrup, a springseated within the cap, an upper springcap supported by the spring, ahook the shank of which passes upward through the springcaps to engagewith a block or plate arranged above the upper spring cap, a projectionformed upon the hook and extending through a slot formed in thestandard, and anti-friction rolls carried by the projection,substantially as described.

projections which extend through slots formed 20 in the standards, andanti-friction rolls carried by said projections, substantially asdescribed.
